YUIOP keyboards are experimental original keyboards designed by KoRoN.
Keyboards in this project are:
-
yuiop27/ - separate keyboard prototype.
27 keys for one hand. single left hand.
-
yuiop54/main - signle board keyboard prototype.
combined right and left-hand boards of yuiop27. PCB dimension is 285.00mm x 94.60mm (GH60 compatible form factor without screw holes).
-
yuiop54/main2 - researching version of yuiop54.
multi-sheets schematic. fix layout for auto routing. introduce GND cupper fill.
-
rev.B - trial to make compatible with GH60 (include screw holes).
use popular keycaps size. tring 128x64 dots OLED.
-
rev.C - key sizes revised version.
consider just layout. use 1u footprint for keys of little fingers. compact form factor size, 267.00mm x 95.00mm (drop compatibility with GH60). change the origin to center of PCB. use 2u for R5 center key. use Edge.Cuts to represents screw holes. OLED is 128x32 dots.
-
rev.D - narrowwer version of rev.C
consider just layout. the dimension is 262.0mm x 95.00mm reduce margins between
F
andG
keys, andH
andJ
keys. -
rev.E - a variation of rev.C
the dimension is 267.00mm x 95.00mm (same with rev.C, not rev.D) make keys on
F
's row be able to use 1.25u keycap.
-
-
yuiop47/ - Single board keyborard with 47 keys.
Shrink from yuiop54. PCB dimension is 214.00mm x 94.00mm
-
yuiop60hh/main - HHKB clone trial
- main2 - HHKB clone trial #2
- main3
- main4
- main5 - Practicing version
- main5b - USB Type-C receptacle version of main5
-
yuiop50d/ - Small footprint, dense 50 keys keyboard.
1u is 16mm, using small keycaps. Standard row staggered layout. Support Pro Micro and RapsberryPi Pico as MCU. PCB dimension is 182.00mm x 103.50mm
-
yuiop63hhs/ - Split HHKB layout minimal keyboard.
No LED nor OLED, Just 63 (29+34) keys. PCB dimension 319.00mm x 95.00mm
- Left 152.50mm x 95.00mm
- Right 162.00mm x 95.00mm
-
yuiop22rs/ - 22 keys + rotary switch macropad.
With OLED, without LED. PCB dimension 95.25mm x 95.25mm
-
contorller/ - Keyboard controler using ATmega32U4 which replacing Pro Micro.
-
yuiopPM/ - Pro Micro compatible but minimal for only keyboard, PCB
-
yuiopPM2/ - Revised version of yuiopPM. It was shelved unfinished.
-
yuiop60hh/main3 - HHKB layout, compatible with popular 60% cases.
Problems on positions of screw hole or so. Not built.
-
yuiop60hh/main4 - HHKB layout, compatible with popular 60% cases.
YUIOP60HH series revision 4. Implemented with MPU ATmega32U4 (not Pro Micro)
-
yuiop31rs/ - 31 keys + rotary switch macropad.
With 31 LEDs (WB2812C-2020). Its hole is too small to be chaged extra on production.
-
yuiop60s/ - split keyboard prototype
-
yuiop60pi/ - PGA2040 (RP2040) base HHKB layout semi-compatible keyboard.
-
yuiop2040/ - Original RP2040 control board.
-
yuiop2040C/ "Compact" model of yuiop2040. Abandoned.
-
yuiop32dm/ - Experimental keyboard for Duplic Matrix
-
yuiopPD/ - Pointing device using the trackball module of Keyball series.
-
rp2040-controller/ - Reusable circuit diagram for controller using RP2040
